Install Control
1. This control can be mounted 0-90 degrees, in any
direction, from the upright position of the gas control
knob, including vertically.
2. Mount the control so gas flow is in direction of arrow on
bottom of control.
3. Thread pipe the amount shown in Table 6 for insertion
into control. DO NOT THREAD PIPE TOO FAR. Valve dis-
tortion or malfunction may result if pipe is inserted too
deeply.
Table 3. NPT Pipe Thread Length in inches.
4. Apply a moderate amount of good quality pipe
compound (DO NOT use Teflon tape) to pipe only,
leaving two end threads bare. On LP installations, use
compound resistant to LP gas (See Fig. 5).
Fig. 5. Use Moderate Amount of Pipe Compound.
5. Remove seals over control inlet and outlet, if necessary.
6. Connect pipe to control inlet and outlet. To tighten inlet
and outlet connections, use wrench on projecting
wrench boss (See Figures 6 and 7).

Connect Pilot Gas Tubing
1. Cut tubing to desired length and bend as necessary for
routing to pilot burner. Do not make sharp bends or
deform tubing. Do not bend tubing at control after
compression nut has been tightened, as this may result
in gas leakage at connection.
2. Square off and remove burrs from end of tubing.
3. Unscrew brass compression fitting from pilot gas outlet
(Figures 6 and 7). Slip fitting over tubing and slide out of
way.
NOTE: When replacing a control, cut off old compression
fitting and replace with new compression fitting
provided on new combination gas control. Never use
old compression fitting as it may not provide a
gas-tight seal. Refer to Fig. 8.
Fig. 8. Always use New Compression Fitting.
